SAMUEL H. DUDLEY, OF MILTON, CONNECTICUT.

IMPROVEMENT IN DIRT-SCRAPERS.

Specification forming part of Letters Patent No. 37,498, dated January27,1863.

To all whom it may concern:

Be it known that I, SAMUEL H. DUDLEY, of Milton, in the county ofLitchfield and State of Connecticut, have invented a new and usefulImprovement in RoadScrapers; and I hereby declare the following to be atrue and exact description of the same, reference being had to thedrawings herewith presented, which drawings constitute a part of thesaid description.

This invention appertains t0 the roadscraper invented by me and patentedon the 6th of June, 1854.

The object of my present improvement is to obviate some inconveniencethat has attended the using of that implement when constructed in itsoriginal form, and to render it more complete and more valuable.

In the drawings, Figure l represents an oblique view of the scraper.Fig. 2 is an end view of the same.

A is the main board or body of the scraper with its draft hooks or bowsH and H attached on the back side and projecting over forward for thepurpose of allowing the load of dirt to be discharged without liftingthe scraper. This was its original form, and it has been found thatsometimes when the scraper was thrown forward to discharge the load itwould fall on its face and endanger the breaking of the handles againstthe stones, and instead of sliding over the dirt it would occasionallycatch a part of the dirt and load up on the back of the board. Now, toavoid any such accidents, I have devised means to prevent the scraperfrom falling at down when thrown forward, and I thereby make it secureagainst any such accidents.

By reference to the drawings it may be seen A is the board. D Dare thehandles. B is the cross-bar. This projects out at each end over the bowsH and H, and having iron rods I and P, which extend downward through thebar and enter into the board on each side of the bows, so that when thescraper is thrown forward the cross-bar rests on the bows, which supportit clear from the ground. The rods P and P can be drawn out wheneveroccasion requires for the purpose of removing the hooks or for replacingthem.

Fig. 3 shows the position of the scraper when thrown forward.

Having thus described my invention and the manner of using it, I do notconfine myself precisely to this form.

What I claim as my improvement on the road-scraper is The arrangementand combination ofthe bar B and the rods P and P, with the bows H and H,or their equivalents, for the purpose and in manner as above set forth.

In testimony whereof I hereto subscribe in presence of two witnesses.

SAMUEL H. DUDLEY.
